The KF airfoil was designed by Richard Kline and Floyd Fogleman. Aircraft wing showing the KFm4 Step. In the early 1960s, Richard Kline wanted to make a paper airplane that could handle strong winds, climb high, level off by itself and then enter a long downwards glide.
A simple folded paper plane Folding instructions for a traditional paper dart. A paper plane (also known as a paper airplane or paper dart in American English, or paper aeroplane in British English) is a toy aircraft, usually a glider, made out of single folded sheet of paper or paperboard.
The name "aileron", from French, meaning "little wing", also refers to the extremities of a bird's wings used to control their flight. [2] [3] It first appeared in print in the 7th edition of Cassell's French-English Dictionary of 1877, with its lead meaning of "small wing".

A paper plane, paper aeroplane (UK), paper airplane (US), paper glider, paper dart or dart is a toy aircraft (usually a glider) made out of paper or paperboard; the practice of constructing paper planes is sometimes referred to as aerogami (Japanese: kamihikÅki), after origami, the Japanese art of paper folding.

A raised aileron reduces lift on that wing and a lowered one increases lift, so moving the aileron control in this way causes the left wing to drop and the right wing to rise. This causes the aircraft to roll to the left and begin to turn to the left. Centering the control returns the ailerons to the neutral position, maintaining the bank angle ...

Since the original Antoinette-style ailerons would have probably been even less effective, unobtrusive "modern" ailerons were inserted – even with these, lateral control remained very poor. [ 4 ] Wing morphing is a modern-day extension of wing warping in which the aerodynamic shape of the wing is modified under computer control.
